Over 400 volumes from Dark Horse Comics (http://goo.gl/Amt0g) are now available in every country Google Play books are sold. Build your tablet comics collection with blockbuster series like Star Wars, Hellboy and more. For a limited time, purchase series for just $3.99 in the US and CA.
It's difficult to browse the comics available from Dark Horse and other publishers like Marvel, because there is no "Comics" category and you can't browse by publisher. I know a new version of Google Play is coming soon and I hope it fixes these problems.
+Scott Miller Other companies (Amazon, Apple, etc.) offer more digital content (ebooks, movies, etc.) than Google, sooner, in more countries and at the same price. Google sucks at negotiating with content providers.
While you can zoom in on comics in Google Play Books, It doesn't auto-track between panels like major players in the digital comics area do (Dark Horse's own app, Comixology, etc). This is purely for reading on a tablet or a PC, not very convenient for trying to read on the go on a phone (even a 5").
